SHEET-METAL-WORKING MACHINE.

'- Specification of Letters Patent. Patented O t, 23, 1917.

Original application filed October 8, 1915, Serial No. 54,757. Dividedand this application filed April 5,

1916. Serial No. 89,047.

To all whom it may concern:

Be it known that I, PETER KRUSE, a citizen of the United States ofAmerica, residing in the borough of Brooklyn, county of Kings, city andState of New York, have invented certain new and useful Improve- .mentsin Sheet-Metal-Working Machines,

of which the following is a specification.

This invention relates to sheet metal work- 'ing machines and aims toprovide certain.

my application Serial Number 54,7 57 filed October 8, 1915. I

An embodiment of the invention is shown in the accompanying drawings.

The invention has been shown as incorporated in a machine for making canbodies. The invention may, however, be otherwise embodied and otherwiseapplied.

in said drawings,-

Figure l is a side elevation of so much of a body-making machine as isnecessary to illustrate the invention;

Figs. '2 and 3 are respectively a vertical sectional view, and a topplan view, illustrating in detail an-embodiment of the improved feedingmeans.

In said drawings, the letter A designates or bench forming the frame ofthe machine, the general construction of the machine being similar tothat described in my United States Patent No. 1,081,050, dated December9, 1913. B is a feed bar working in a suitable guide-way in the top faceof the table A (there being'usually a plurality ofsuch feed bars), thefeed bar being preferably attached to a slide block or piece 0, andadapted to be reciprocated by a suitable means, as for instance, a trainof links and levers b b 72 connected to a crank pin 6 upon a disk I)mounted upon a main drive-shaft D. The feed bar or bars B are providedwith feed. fingers E.

The arms E are pivoted upon the feed bars B as at e, and are adapted-tobe depresse against the pressure of a spring a as they move rearwardly,being so depressed is a flanging mechanism by which flanges or hooks areformed on the notched sides of the sheets, and F is a body forming Imechanism comprising a horn G around which the sheets are bent and theends interlocked and joined in well-known manner. The function of thefeed mechanism is to feed the sheets of metal to an exact position withrelation to these several mechanisms F F ,-and F it being essential tothe formation of a can that the sheets be operated uponv at precisepoints by the several mechanisms, and that the ends of the sheets andthe notches therein shall properly match when wrapped around the hornand the ends joined. 7

.Sheets of meta are fed to'the machine in any suitable manner (by handif desired), and are carried forward by the feed fingers upon successivereciprocation of the cod bars B. An automatic feed I is shown, theconstruction of which is fully described in Patent No. 1,081,050aforesaid. As the feed bars B move forward, the sheets of metal Xarecarried forward by the. feed fingers beyond stops H H and H mounted upona fixed part of the machine. The sheets of metal are preferably movedslightly beyond the stops, ment of the feed fingers are movedrearwardlyagainst the stops H H or H by suitable means, as by the meansP illus-' trated herein,

As shown, the means P may comprise a bar or blade p havinga cam face 12thereon. The bar 2 is adapted to move or reciprocate vertically, and tothis end it may conveniently be mounted upon a reciprocating part of thenotching mechanism F (or the moving part ,of a'nother mechanism), asillustrated at 10 The ;'means P act to push the sheet rearwardly againstthe stops -H Strips b are preferably provided, which are adapted to bearupon the upper sides of the sheets X with slight friction, the friction,however, not being suficient to prevent the feeding or positioningmovements of the sheets.

The operation of the device is as follows :--The sheets of metal areengaged by the feed fingers E, and are carried forward beyond, andpreferably slightly beyond, the stops H H or H The sheets are then actedupon by the means P and pushed rearwardly against the stops. en inposi-- tion with reference to the mechanisms 18, F and F, the sheets aresuitably acted upon by said mechanisms,

The inventive ideas are capable of receiving other embodiments thanthose specifically illustrated and described.

What is claimed is 1. ][n sheet metal working machines, combination of afeed means adapted normally advance a sheet of metal beyond apredetermined position, means adapted to operate against the advanceperipheral edge of the sheet to position said sheet by moving itrearwardly, and means for moving said positioning means transversely ofand out of the path of said sheet to permit the feeding of said sheetforwardly to another working position.

2. In sheet metal working machines, the combination of a feed meansadapted to normally advance a sheet of metal beyond a predeterminedposition, a stop, aneans adapted to operate against the advanceperipheral edge of the sheet to position said sheet by moving itrearwardly against said the intense stop, and means for moving saidpositioning means transversely of and out of the path of said sheet topermit the feeding of said sheet forwardly to another working position.

3. ln sheet metal working machines, the

combination of a feed means adapted to normally advance a sheet of metalbeyond a predetermined position, a stop for pre- I reciprocating workingpart, and a set-back' finger carried by said reciprocating part, adaptedto operate against the advance peripheral edge of the sheet toaccurately position said sheet by moving it rearwardly,

In sheet metal working machines, the

said reciprocating part carrying said setback means out of the path ofsaid sheet to permit the feeding of said sheet forwardly to anotherposition beyond said working mechanism.

In witness whereof, l have hereunto signed my name in the presence oftwo subscribing witnesses.

' PETER KRUSE.
